look up any word, like jamflex:
 
1.
When something truly amazing happens.

Highest form of praise.
Girl: I dont have sex on the first date..
Boy: Oh Ratsbum!
Girl: But ill give you head
Boy: Un-Ratsbum!

When charlie found the golden ticket, it was a miracle.When he was given the chocolate factory, it was Un-Ratsbum

The feeling of Euphoria can also be defined as Un-Ratsbum

Scarlet Johanson is Very Un-Ratsbum

"That new bar in town is Un-Ratsbum"

"That girl is so Un-Ratsbum!"

Person 1: There's nothing to do tonight.
Person 2: Hmmm...
Person 3:"I know!...(pulls out a bag of weed)
Everyone: "Un-Ratsbum!"

The philosophy of Ratsbum/Un-Ratsbum:

One mans Ratsbum is another mans Un-Ratsbum.

Stealing someones girl in town. Ratsbum for him, Un-Ratsbum for you.

Seeing someone walk into a pole. Ratsbum for them, Un-Ratsbum for you!
